1 Claim.

This invention relatesto a rotary support for motor vehicle radiators sothat the radiator under treatment may be filled with a vcleaningsolution and the support rotated to cause the cleaning liquid to beslushed from one end of the radiator to the other, dislodging theforeign matter from the tubes thereof.

An important object of this invention is to provide a device of thischaracter including clamps which may be operated to securely clamp aradiator in position for cleaningv Still another object of the inventionis to provide means whereby the speed of rotation of the rotary support,may be varied to meet various requirements.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts hereinafter more fully describedand pointed out in the claim, it being understood that changes may bemade in the construction and arrangement of parts without departingpfromthe spirit of the invention as claimed.

Referring to the drawings:

Figure l is a front elevational view of a radiator support constructedin accordance with the invention, and illustrating a radiator aspositioned on the support.

Figure 2 i a plan view thereof.

Figure 3 is an end elevational view of the device.

Figure 4 is an enlarged sectional view through a support, andillustrating a modification comprising a pair of clamping members forclamping radiators at opposite sides of the support.

Figure 5 is a sectional view taken on line 5-5 of Figure 2.

Referring to the drawings in detail, the device comprises a supportembodying leg members 5, secured together, by means of the brace bars 6.As shown, the leg members are connected at their upper ends and areprovided with bearings l, where the leg members verge. Mounted betweenthe leg members, is a rectangular frame 8 which includes rigid side bars9 and end bars ID. A pivoted bar H is pivotally secured to the end barl2 by means of the pivot pin 2i), the bars l2 and I2 being secured tothe frame 8. The lower end of the, bar II is extended at right angles tofit against the bar 12 where it is secured in position by means of thebolt 2|, thereby providing means to permit a radiator to be readily andeasily removed or secured to the frame by merely removing the bolt 2|and swinging the bar H to the dotted line position as shown in Fig. 2 ofthe drawings. Shafts l3 are secured to the end bars 'i'flof the frame,and operate in the bearings 1, as clearly shown by Figure 1 of thedrawings, so that the frame may rotate freely.

The pivoted bar I! is formed with a threaded opening, through which thethreaded portion 14 of the screw clamp stem [5 of the clamp i6, ismounted, there being provided a clamp handle it at one end of the screwclamp stem for operating the screw clamp. One end of the screw clampstem is formed with a head l1 fitted in the socket l8 formed on theclamp l1 whereby the stem [5 may be rotated with respect to the memberl8.

The reference character I? indicates a removable member of the screwclamp, which member is adapted to rest against the radiator undertreatment and force the radiator into close engagement with therectangular frame 8. Supported at one end of the device, is a platform18 which provides a support for the motor H] which transmits movement tothe pulley 20 through the belt 2|, the pulley 20 being mounted on theshaft 22 that in turn is mounted in bearings formed at the upper end ofthe support 23. A substantially small pulley 24 is also mounted on theshaft 22 and transmits movement to the larger pulley 25 through the belt26. The pulley 25 is mounted on one end of the shaft 21 which in turn isprovided with the gear 28 that meshes with the gear 29 mounted on oneend of the shaft 30. The shaft 30 transmits movement to the shaft l3 atone end of the rectangular frame 8, through transmission gearing that iscontrolled by means of the lever 3|, to the end that the frame 8 may berotated at various speeds, to meet variou conditions.

In the form of the invention as illustrated by Figure 4 of the drawings,the rectangular frame which is mounted for rotary movement within thesupport 32, is indicated by the reference character 33. Extending fromopposite sides of F the frame 33 adjacent to the ends thereof, are

bars 33 that are connected by the cross bars 34 disposed at oppositesides of the frame. The cross bars 34 have threaded openings to receivethe threaded portions 35 of the screw clamp stems 35 which are disposedon opposite sides of the frame 33. Thus it will be seen that due to thisconstruction, a radiator such as indicated at 31 may be positionedagainst each side of the frame 33 and clamped in position, by means ofthe clamps 38 carried at the inner 3 ends of the screws 36. Thisstructure is provided, so that two radiators may be treatedsimultaneously.

In use a radiator to be cleaned, is filled with cleaning solution andthe outlet and inlet openings thereof are plugged to retain the solutionin the radiator.

The motor I9 is then started and a rotary movement is transmitted to therectangular rotary frame in a manner as described. During the rotationof the frame and radiator, the cleaning liquid is sloshed Within theradiator causing the foreign matter closing the tubes of the radiator,to become dislodged.

What is claimed is:

A device for supporting motor vehicle radiators while being flushed,comprising a support, a rectangular frame mounted for rotary movementWithin the support, said frame embodying side bars against which aradiator is positioned, a screw clamp supporting bar having one of itsends pivotally connected to the frame the opposite end of the bar beingremovably secured to the frame, said bar having a threaded openingdisposed intermediate its ends, an adjustable screw clamp including athreaded portion operating through the threaded opening of the bar, awide radiator clamping member adjustably mounted at one end of the screwclamp, said wide clamping member adapted to clamp a radiator against theside bars of the frame, whereby the frame and radiator supported therebymay be rotated agitating flushing fluid contained within the radiator.
